　　The steel die surface of the magnetic box should be flat, and cleaned up before each use. There should be no concrete residue or other particles, so as not to affect the connection between the magnetic core and the die plate, and affect the fixing strength.
　　Before and after use magnet box , the contact surface of the magnetic core must be cleaned, and there must be no concrete or iron filings sticking on the surface, which will affect the adsorption force.
　　Clean the concrete and oil on the assembly regularly, and oil the guide bar regularly to ensure the smooth opening and closing of the core.
　　Do not use hammer and other hard objects, or free fall to the steel surface, otherwise the magnetic core itself strong adsorption may damage the use of the box, or even cause the magnetic core dislocation, damage the magnetic box.

With the development of the construction industry, precast concrete has been regarded as a new generation of construction materials. This construction method has been widely used in many countries around the world. Precast shuttering magnets are one of the most important accessories for precast concrete formwork. It can fix the side rails when pouring concrete to prevent cement from flowing out. SAIXIN shuttering magnets are suitable for various formwork structures such as wood formwork and steel formwork.
It consists of a switchable neodymium shuttering magnet unit, shell with magnetic block and fixing screws .The neodymium magnet and steel plate form a magnetic circuit with a strong attraction force, which is used to fix wooden or steel formwork.There is a control button on the top of the precast concrete magnet. When you press the button, this magnet uses the magnetic circuit holds the formwork firmly on the steel plate.
When you turn off the button, you can easily change magnets position. The two universal threaded holes on the top of the formwork magnet can be equipped with various adapters. You can use our products according to your needs.

In the construction industry, traditional wooden formwork has been widely used to support concrete pouring. However, this traditional formwork system has some inherent problems, such as time-consuming installation and dismantling, vulnerability to damage, and the requirement of significant manpower. To solve these issues, an innovative construction solution has emerged – Shuttering Magnet.

When purchasing shuttering magnet with reliable quality for PC components in the situation of uneven product quality and lack of industry standards in the market, the following aspects can be considered:
1.Brand
• In the prefabrication construction industry where there is fierce competition with inconsistent product standards and issues like low price and low quality, choosing suppliers with brand influence is a top choice when there's no product trial comparison.
• Among many brand suppliers, it's necessary to comprehensively consider the plant equipment, production capacity, qualification certificate, quality control and R & D team of each brand supplier according to the enterprise's own development plan.
2.Quality
1)Magnet Block
• Magnetic block is the core of the shuttering magnet, and the magnet within it is crucial. The quality of the magnet impacts the suction of the shuttering magnet , and the coating (anti-corrosion) and metal protective layer (anti-scratch) of the magnet affect its service life. Both aspects are essential. To detect the actual working suction of the shuttering magnet, professional testing equipment is needed, like the suction testing equipment before the shuttering magnet leaves the factory and the testing equipment for testing the suction (as shown in relevant figures).
2)Shell
• Currently, the shell materials of shuttering magnet available on the market are mostly steel Q235 and stainless steel 201 , 304 , 316 . Generally speaking, the thickness of the shuttering magnet plate ranges from 3 to 4 millimeters.
• When it comes to strength, steel Q235 will be better than stainless steel. However, in terms of anti-rust performance, stainless steel performs better than high-strength carbon steel. When making a purchase, you can select the appropriate material and thickness based on the actual usage scenarios.
• Moreover, attention should also be given to the frame structure of the shell. The structure that incorporates a reinforcing plate and bolt design is stronger and more durable compared to the one with direct welding.

3)Accessory
Saixin has visited numerous component factories and witnessed a large number of shuttering magnet . However, various quality issues have emerged because the quality of the selected accessories fails to meet the required standards.
The auxiliary accessories for shuttering magnet include switch indenters, springs, bolts, stainless steel rings, and so on. When making purchases, special attention must be paid to the quality of these accessories. For instance, one should focus on the dimensional accuracy of switch indenters, the performance grade of bolts, and whether the springs conform to the national standards.
The production of shuttering magnet must have standardized quality inspection procedures that cover everything from raw material procurement to processing and assembly. For example as shuttering magnet , the quality inspection procedures typically involve the following steps:
IQC (Incoming Quality Control) --- Inspection of semi-finished products --- Inspection of finished products ---- Incoming test --- OQC (Outgoing Quality Control)
Even a shuttering magnet has to pass all these tests from the stage of raw materials to becoming a finished product before it can be judged as a qualified product. If we compare the shuttering magnet to a car, the magnetic block is like the engine, which is the core component of the entire product. The switch pressure head is analogous to the steering wheel as it controls the working direction of the whole product, while the shell and screws are equivalent to the frame parts. Just as with a car, for a complete shuttering magnet, the quality of all accessories cannot be overlooked. If there is a problem with any one accessory, it will impact the working performance of the entire product. Therefore, when making purchases, we should opt for products from brands that have passed qualified quality inspections instead of blindly chasing low prices and choosing inferior products.

3、Model and Quantity
Once the supplier of shuttering magnet has been selected, the next step is to determine how to choose the appropriate shuttering magnet. This demands a comprehensive consideration of various aspects in the production process of precast concrete products, such as the usage scenarios of magnetic fixed products (whether for fixed formwork or vibrating formwork), the spacing of reinforcements, the temperature inside the steam curing kiln, the height of the mold, and the specifications and models of embedded parts, etc.
Take the shuttering magnet as an example. When laminated plates are produced on the fixed die table, it is recommended to use shuttering magnet with a suction force ranging from 600 to 800 kg. The service spacing of the shuttering magnet (generally between 1 and 2 meters) can be adjusted according to the height and thickness of the die.
In the production process of the assembly line vibration die, shuttering magnet with a suction force of 1000 kg can better meet the production requirements. When manufacturing wallboards, 1350 kg magnetic boxes can be chosen. And when producing prefabricated beams, columns or other special-shaped components, shuttering magnet with a suction force ranging from 1800 to 2100 kg can be selected and used in combination with corresponding fixtures.
With these basic data at hand, we are able to analyze the total quantity and budget for the shuttering magnet needed by a specific project.

April.2025 , The Chinese Ministry of Commerce has released Document No.18 ,Implement export controls on heavy rare earth related items .

So recently Chinese Customs conducts strict inspections on the export of heavy rare earths . many products can be not shipped out , or being detained at customs for inspection .

How should we deal with it under such strict export control ?


Firstly , we are actively looking for magnet without controlled elements , useing qualified magnet to do mass production .



Secondly , we can apply for Export License for Dual-use Items and Technologies of PRC . But this requires strong cooperation from our customers , because we need to provide information about the customer’s company , proof of end use (must be original and stamped for return),and a series of files . The approval time will be relatively after all files are provided , which is 45 working days . So we suggest our customer prepare in advance .



Due to the strict control now , many forwarders do not accept scattered goods , so we also suggest that you can place more orders at one time , and determine a full container shipment .


However , even if we fully prepared , there is still a possibility of customs inspection , so pls all customers who place orders can wait patiently , leave enough time for factory to arrange the shipment
